 add HttpClient accessor apis
+
+These apis allow you to easily send requests without first accessing the `HttpClient` service.
+
+Below is an example of using the `get` accessor api to send a GET request:
+
+```ts
+import { FetchHttpClient, HttpClient } from "@effect/platform"
+import { Effect } from "effect"
+
+const program = HttpClient.get(
+  "https://jsonplaceholder.typicode.com/posts/1"
+).pipe(
+  Effect.andThen((response) => response.json),
+  Effect.scoped,
+  Effect.provide(FetchHttpClient.layer)
+)
+
+Effect.runPromise(program)
+/*
+Output:
+{
+  userId: 1,
+  id: 1,
+  title: 'sunt aut facere repellat provident occaecati excepturi optio reprehenderit',
+  body: 'quia et suscipit\n' +
+    'suscipit recusandae consequuntur expedita et cum\n' +
+    'reprehenderit molestiae ut ut quas totam\n' +
+    'nostrum rerum est autem sunt rem eveniet architecto'
+}
+*/
+```
